As embedded electronic control systems are increasingly penetrating vehicle subsystems, the designers are faced with a dilemma of providing state of art vehicle features on one hand and ensuring frugal implementation of the same to meet competitive pressures on the other. For embedded software and hardware systems this means adoption of judicious and innovative design choices with reusable building blocks. This paper dwells upon various design aspects of control and monitoring which are frequently used for automotive applications such as feed-forward and proportional integral control, diagnostics for sensor boundary conditions, handling of intermittent faults without causing nuisance to the vehicle users etc.

Deep Learning Based Real Time Vulnerability Fixes Verification Mechanism for Automotive Firmware/Software

2021-01-018304/06/2021

Software vulnerability management is one of the most critical and crucial security techniques, which analyzes the automotive software/firmware across the digital cockpit, ADAS, V2X, etc. domains for vulnerabilities, and provides security patches for the concerned Common Vulnerabilities and Exposures (CVE). The process of automotive SW/FW vulnerability management system between the OEMs and vendors happen through a channel of fixing a certain number of vulnerabilities by 1st tier supplier which needs to be verified in front of OEMs for the fixed number and type of patches in there deliverable SW/FW. The gap of verification between for the fixed patches between the OEMs and 1st tier supplier requires a reliable human independent intelligent technique to have a trustworthiness of verification. Hence, in this regard, a novel machine learning based intelligent verification technique is proposed which is free from human intervention to verify the certain number and type of vulnerabilities

21TOFHP02_0902/01/2021

Digital technology is rapidly transforming off-highway equipment, giving users more functionality and higher precision than is possible with human operators. John Deere highlighted its advanced electronic skills during the virtual CES 2021 conference in January by giving remote booth attendees virtual reality (VR) headsets that demonstrated its technical prowess. Deere highlighted its ExactEmerge planter technology and its 8RX track-type tractor during the virtual trade show. The two can be paired to boost yields, letting operators plant seeds with high precision even while running at 10 mph (16 km/h), double the rate possible with earlier generations.

Application Layer - Diagnostics

J1939/73_202006 (Historical)06/09/2020

SAE J1939-73 defines the SAE J1939 messages to accomplish diagnostic services and identifies the diagnostic connector to be used for the vehicle service tool interface. Diagnostic messages (DMs) provide the utility needed when the vehicle is being repaired. Diagnostic messages are also used during vehicle operation by the networked electronic control modules to allow them to report diagnostic information and self-compensate as appropriate, based on information received. Diagnostic messages include services such as periodically broadcasting active diagnostic trouble codes, identifying operator diagnostic lamp status, reading or clearing diagnostic trouble codes, reading or writing control module memory, providing a security function, stopping/starting message broadcasts, reporting diagnostic readiness, monitoring engine parametric data, etc. California-, EPA-, or EU-regulated OBD requirements are satisfied with a subset of the specified connector and the defined messages.

Automated Generation of AUTOSAR ECU Configurations Using Xtend: Watchdog Driver Example

2020-01-133504/14/2020

Automotive Open System Architecture (AUTOSAR) is a system-level standard that is formed by the worldwide partnership of the automotive manufacturers and suppliers who are working together to develop a standardized Electrical and Electronic (E/E) framework and architecture for automobiles. The AUTOSAR methodology has two main activities: system configuration and the Electronic Control Unit (ECU) configuration. The system configuration is the mapping of the software components to the ECUs based on the system requirements. The ECU configuration process is an important part of the ECU software integration and generation. ECU specific information is extracted from the system configuration description and all the necessary information for the implementation such as tasks, scheduling, assignments of the runnables to tasks and configuration of the Basic Software (BSW) modules, are performed. The ECU configuration process involves configuring every single module of the AUTOSAR architecture. Due

Overcoming Operational Blindness in Software Architecture

2020-01-133604/14/2020

A lesson learned on why software architects fall short of expectations and how to fix it by changing the focus. Detailing the design that is already clear in the head comes natural to an architect. Afterall most architects are basically aged developers. Consequently, this haste to get started - and even excitement about the technical challenges - prevents them from being effective. This paper is about the two small parts which make a developer become an architect: Discipline and Scope. The following chapters cover the challenges as well as the lessons learned in the development of an embedded automotive software architecture. Based on the experience from different embedded applications the following structure will be followed: Part 1: Where to start with a new design This is the main question asked by new software architects. A good design starts with a clear value proposition. What is the goal and scope of the architectural design? Different answers are discussed and a good example

Model-Based Design of Service-Oriented Architectures for Reliable Dynamic Reconfiguration

2020-01-136404/14/2020

Service-oriented architectures (SOAs) are well-established solutions in the IT industry. Their use in the automotive domain is still on the way. Up to now, the automotive domain has taken advantage of service-oriented architectures only in the area of infotainment and not for systems with hard real-time requirements. However, applying SOA to such systems has just started but is missing suitable design and verification methodologies. In this context, we target to include the notion of model-based design to address fail-operational systems. As a result, a model-based approach for the development of fail-operational systems based on dynamic reconfiguration using a service-oriented architecture is illustrated. For the evaluation, we consider an example function of an automatically controlled braking system and analyze the reconfiguration time when the function fails. The reconfiguration time, together with the worst-case execution time (WCET), was determined by a model-based calculation

Selftrust - A Practical Approach for Trust Establishment

2020-01-072004/14/2020

In recent years, with increase in external connectivity (V2X, telematics, mobile projection, BYOD) the automobile is becoming a target of cyberattacks and intrusions. Any such intrusion reduces customer trust in connected cars and negatively impacts brand image (like the recent Jeep Cherokee hack). To protect against intrusion, several mechanisms are available. These range from a simple secure CAN to a specialized symbiote defense software. A few systems (e.g. V2X) implement detection of an intrusion (defined as a misbehaving entity). However, most of the mechanisms require a system-wide change which adds to the cost and negatively impacts the performance. In this paper, we are proposing a practical and scalable approach to intrusion detection. Some benefits of our approach include use of existing security mechanisms such as TrustZone® and watermarking with little or no impact on cost and performance. In addition, our approach is scalable and does not require any system-wide changes

Research on the Enhanced ADAS Functions with Modular Design Based on 5G-V2X Technology

2020-01-502602/24/2020

This paper will mainly discuss the effect of the combination of the 5th generation wireless systems - Vehicle to Everything (5G-V2X) technology an Advanced Driver Assistance Systems (ADAS) functions. With the promotion and popularization of 5G technology with high bandwidth and bottom delay, V2X has been able to quickly and safely transmit more information to target vehicles in need in the field of automatic driving. Traditional ADAS functions development has been carried out for decades, but there are still many unsolvable problems in perception and decision-making. In this paper, V2X technology is introduced into the auxiliary driving functions of L0-L3 stage by using the idea of platform module design. On the basis of not redeveloping the original functions, the existing problems of perception and decision-making are improved. Through the experimental demonstration in this paper, this method can indeed save the development cost and shorten the development cycle.

Autonomous Vehicles Scenario Testing Framework and Model of Computation

12-02-04-001512/18/2019

Autonomous Vehicle (AV) technology has the potential to fundamentally transform the automotive industry, reorient transportation infrastructure, and significantly impact the energy sector. Rapid progress is being made in the core artificial intelligence engines that form the basis of AV technology. However, without a quantum leap in testing and verification, the full capabilities of AV technology will not be realized. Critical issues include finding and testing complex functional scenarios, verifying that sensor and object recognition systems accurately detect the external environment independent of weather conditions, and building a regulatory regime that enables accumulative learning. The significant contribution of this article is to outline a novel methodology for solving these issues by using the Florida Poly AV Verification Framework (FLPolyVF).
